This compound is used in the production of printed circuit boards. It's also in flame retardant materials because it lowers the combustion temperature and increases the production of residues or chars. Ammonium sulfate activates yeast, so it helps to get industrially produced bread to rise, and it's also a generalpurpose food additive.

Jun 18, 2010· The normal production route taken is to refine the bauxite to aluminium oxide, or alumina [Al2O3], which is a white, crystalline powder. This powder is then smelted to form aluminium metal. As a general rule, four tonnes of dried bauxite is required to produce two tonnes of alumina, which in turn provides one tonne of primary aluminium metal.
